[athani] Add a simple tool to list and control ANI parameters.
This is a WIP tool I'm using to figure out why ANI is weirdly busted in my home FreeBSD AP/STA setup. Although athstats (mostly) gets the ANI statistics correct, ANI is making the radio deaf it doesn't recover without being disabled. It's very WIP. Tested: * Carambola 2, (AR9331), AP/STA mode.
